Rate Schedules & Tariff Analysis
STEMC's C&I rates reflect TVA wholesale pricing plus the cooperative's distribution costs, adjusted monthly via the TVA Fuel Cost Adjustment. Larger classes (GSA2, GSA3) shift cost recovery from energy to demand charges, so load factor and peak demand management are the primary cost levers. GSA3's low 8.281 cents/kWh energy charge rewards high-load-factor industrial operations that spread demand.
Southwest Tennessee Electric Membership Corporation Rate Schedule List
| Schedule | Applicability |
|---|---|
| GSA1 | Small commercial / general service |
| GSA2 | Medium commercial (demand up to ~1,000 kW) |
| GSA3 | Large commercial / industrial (demand + contract demand) |
Southwest Tennessee Electric Membership Corporation Rate Features & TOU Details
- Three commercial/industrial classes: GSA1 (no demand), GSA2 and GSA3 (demand-metered)

Southwest Tennessee Electric Membership Corporation Data Access FAQ
Can a third party get my facility's usage data programmatically?▾
No. STEMC offers no Green Button, EDI, or public API. Third-party access requires a written customer authorization and a manual data export negotiated with STEMC Member Services or the VP of Operations (731-585-0502); there is no published SLA.
What usage granularity is available for C&I accounts?▾
Daily usage only, via the MyUsage app (smart-meter readings transmitted once daily). STEMC does not provide 15-minute, 30-minute, or hourly interval data.
Which rate class applies to my business?▾
Small/general-service load uses General Power 1 (GSA1, no demand charge). Medium demand-metered load uses GSA2 (demand up to ~1,000 kW). Large/industrial load uses GSA3, which has the lowest energy rate but tiered demand and contract-demand charges.
Why do my rates change every month?▾
STEMC resells TVA power and applies TVA's Fuel Cost Adjustment, which is recalculated monthly to recover fuel and purchased-power costs that vary with weather and market conditions. A new rate sheet is published each month.
Is there a competitive supplier I can switch to?▾
No. As a TVA distributor and electric cooperative, STEMC is the sole electricity provider in its territory. Tennessee does not offer retail electric choice for cooperative members.
How can a business get CSV or Excel billing data?▾
Contact STEMC and ask for the VP of Operations (731-585-0502) or the Manager of Business Services to request a manual CSV/Excel export. Format and cadence are negotiated case-by-case; there is no self-service export.
